I V V a Figure 7 is a vertical and axial sectiontaken on the line AA of Figure 6, and illustrates the position of thereamer partly I entered inthe bushing. p

F lgure 8 is a front elevation of the ream ing device showing the slowspeed drum with gear of a Ford automobile transmission, fixed inposition thereon. i w

Figure 9 is a vertical axial-section taken on the line'B B of Figure 8,and shows a smaller reamerthan thatshownin Figure 7, p

signed for this particular purpose, but' having its main shank thesamesize as the reamers shown in Figures 7 and 9. I

Figure 12 is'a front elevation showing the triple gear-of a Fordautomobile transmission fixed in position thereon, in connection withthe yokeshown in Figure 4.

v Figure 13 is a vertical axial section taken on the line.DD of Figure12, illustrating the position of the gear thereon, together with thespecial reamer requiredfor this purpose, and-having a shank of thesamediameter as the shanks of the reamers shown in Figures 7', 9 and 11.Figure 14 is a perspective view of the bar previously forced into.thereof, and illustrates the special reamerdewrench. used to turn anyof the reamers shown in the figures.

In the figures, the reaming machine is -shown to be made practically ofa single casting with a few attachments, wherein the base 1,hasprojecting above it ,,a disk portion 2, having a flange 3, which. ismachine faced on the surface4, aswell asvupon the interior cylindricalsurface 5, and also upon the fiat zones6 and 7, of the inside of thedisk portion 2. The upperpart of the flange 3? is separated fromthe diskortion 2, by a saw cut 8. The portion 3 1s ivided at the top, where eachpart terminates in an upstanding Year 9., These ears are, adjustably ortd t g ther. by meansof the bolt 10, and;

- the bolt and in contact with one of the ears 9. The flange 3 hasperforated cars 12 and 13 for the reception of clamping hooks 14 and 15,each having a thumb screw 16. concentrically positioned with respect tothe cylindrical surface 5, is the cylindrical pocket 17, having amachined cylindrical surface 17*, which truly concentric and coaxialwith the cylindrical surface 5. Extending to the rear of the pocket 17.,is the long cylindrical hole 18, the surface of which is machinedco-axial with the surface 5. web 19 extends up from the base 1 and isincorporated with the walls of the pocket 17 and of the hole at 18.

In Figure 4 is shown a yoke 20, having a central hole at 21, flanged at22. The body of the yoke 20 has a flange extending from the surfacethereof in theopposite direction to that of the flange 22. The length ofthis yoke 20 is such as to be engaged be tween and by the hooks 14 and15, when a piece, engaging the surface 17, and having its largestdiameter smaller than that of the surface 5, is positioned upon thereaming machine.

The Figures 6 to 13 inclusive show the device illustrated in Figures 1to 5 inclusive, having various parts of a Ford transmissionconcentrically and co-axially held thereon for the reaming of thebearings. In Figures 6 and 7 is shown the reverse transmission drum 2 1of a Ford automobile, having a bushin 25 to be reamed (o-axial with theperipheral cylindrical surface 26, which surface co-fits with thecylindrical surface 5, of the reaming machine, having a flange 27 fullyin contact with the flat surface 4. The cars 9 are'drawn together byturning the wrench 11, so as to fix the drum firmly and co-axiallywithin the machine. Previous to putting the drum 24 in place, as justdescribed, the reamer 28 is positioned, having its shank 29 in slidingand turning engagement with the cylindrical surface 18 of the machine.The shank 29 terminates in engagement with the bar wrench 30 for turning the reamer. The hooks 14 and 15 are used in positioning and holdingthe drum 24 in place against the surface it.

Referring now to Figures 8 and 9, which illustrate the slow speed drumgear of a Ford transmission in place on the reaming machine, wherein theslow speed drum 31 replaces the reverse drum shown in Figures 6 and 7,and wherein the bushing 32 is to be' reamed, the realner 33, requiredfor the slow speed bushing is smaller than that required the reversedrum bushing, but has a 'shank 345 of the same "diameter as the shank29'fittiiig the same hole.

Referring now to Fi'gure'slO and 11, which concern the reaming of thetransmission brake drum '35 of a' Ford automobile, the

periphery of this drum is the same as that of the reverse and slow speeddrums, and consequently adapted to fit within the surface 5, and to beclamped therein by means of the clamp at 9. The drum 35 has acylindrical projection 36, in the outer end of which, is the flangelessbushing'37, and at the inner end of which is the flanged bushing 38.Each of these bushings has the same internal diameter and is forced intothe place shown in section in Figure 11. The reamer in this case issomewhat differently constructed than the reamers shown in Figures 7 and9, in having in addition to the shank 39 which is the same diameter asthat of the shanks 29 and 34, a shank portion 40, of a diameter equal tothe finished diameter of bushing 38, as left by the reaming portion 41,and serves as a guide to the reamer, when Referring to Figures 12 andthere is shown positioned upon the reaming machine a triple gear 42,wherein the smaller gear 1-3, of the three gears, has a sliding fitconcentrically and co-axi'ally within the. cylindrical surface 17, ofthe pocket 17. The central or larger gear 44, is in contact with thezone surface '7 of the machine. In order to hold this gear in thisposition upon the machine, the yoke 20 is made to engage the triplegear, having its flange 22 in engagement withan annular recess in thegear 45. The yoke-2O is clamped into place at its ends by the hooks 14Land 151 The reamer in this case has a shank 16. which'has the samediameter as the shanks 29, 34-and 39, shown in the other figures-and thereaming portion 4-7 is 'of the desired size to ream the bushing 48 ofthe gear.

The operation 'of this device has, been somewhat indicated in connectionwith the description of the figures, wherein the shanks of various sizedreamers are all the same diameter for a proper sliding fit with the boreof the hole 18, the walls of which, act as a guide to the rea-mers inmaintaining the same, concentric and coaxial tothe piece to be reamed,when held concentrically in position upon the machine.

Modifications of the one embodiment of this device herein shown anddescribed, may be made without departing from the spirit and scope of myinvention, '1 therefore, do not wish to be confined to the oneembodiment, hence I claim. V 7
